Using ISO as your only control to influence the brightness of the final image.

Why? Why I'm supposed to use something so un-photographic for photography?

What ISO? Based on 106%, 170%, or something else?

What about clipping?

Don't you know that raising ISO setting is just like using faster film, last resort?

What is brightness of the final image, brightness where, in midtone? Quite often we want to bring more contrast to midtones, not more brightness; but not to dig into the shadow noise and colour artifacts. Final image is about characteristic curve, brightness is meaningless.

Relax!

I do not need your advice Especially because your remote diagnostics missed the target.
